China's Ministry of Commerce on Wednesday released questionnaires requiring some US semiconductor firms for information on sales activities in China, including cost and profit comparisons between their operations in the US and China.

The forms also ask for names of Chinese customers, transaction details, and raw material supplier information as part of an anti-dumping investigation.

Companies have 37 days to respond, Bloomberg reported.

Though specific firms haven't been named, products are typically supplied by companies like Texas Instruments (TXN) and Analog Devices (ADI), Bloomberg reported.

The investigation targets analog IC chips, which are key components in electronics such as smartphones, EVs, and medical devices, despite the fact that they do not require cutting-edge manufacturing, the Bloomberg report said.

Texas Instruments and Analog Devices did not immediately respond to MT Newswires' request for comment on the matter.
